MIC29311

3A Fast-Response LDO Regulator for

USB

General Description

Features

The MIC29311 is a 3A, fast response, low-dropout (LDO)

voltage regulator. Using Micrel’s proprietary Super βeta

PNP™ process, the MIC29311 offers exceptional dropout

(600mV at 3A) and low ground current (60mA at 3A). Fast

transient response allows it to recover quickly from large

load changes while maintaining a steady output. The

device can be sent into a “zero-current” off mode when the

TTL compatible enable is brought low.

• Fast transient response

• 3A output current over full temperature range

• 600mV dropout voltage at full load

• Low ground current

• 3% total accuracy

• “Zero” off-mode current

• Thermal Shutdown

Designed specifically for Universal Serial Bus (USB)

applications, the MIC29311 works with USB power

switches to provide an economical solution for self-

powered hubs. The 5.1V output voltage is optimized to

work with lower-cost high on-resistance USB power

switches (300mΩ) to provide a minimum of 4.75V at

500mA to downstream ports. Used with MIC2527 quad

USB power switches, the MIC29311 can power up to 6

downstream ports.

• Current Limiting

• Reversed battery protection

• Fixed 5.1V Output

Applications

• Self-powered USB hubs

• USB power switching

Features of the MIC29311 include thermal shutdown,

current limit, reversed-battery and reversed-lead insertion

protection. An overvoltage clamp is available to maintain a

safe output when the input voltage exceeds 8V. An error

flag is also available to indicate of the output falls out of

regulation, or when an overcurrent condition occurs.

• High-efficiency linear power supplies

• High-efficiency switching supply post-regulator

The MIC29311 is available in a 5-pin TO-220 or TO-263

package with a fixed 5.1V output voltage.

For other high current, low-dropout voltage regulators,

please see the MIC29150/300/500/750 and the MIC29310,

MIC29510, MIC29710.
